MarsSeed [1] filed a deletion request for python2-www-authenticate [2]: I suggest this package can be deleted. Its only AUR dependent is the broken python2-requests-negotiate (discontinued in 2017; deletion request submitted) This project has also been discontinued in 2019. Even its Python 3 based version is not depended upon by anything: https://aur.archlinux.org/packages/python-www-authenticate Safe to delete. No package needs this deprecated library anymore.
